CO_TXT_OUTBINDING_NOT_FOUND

I need your help on Idoc-to-file scenario using Business Service with Party. My Problem is that the Receiver Interface and Receiver Namespace in SXMB_MONI appear same as that of senders and the message goes into the error condition "CO_TXT_OUTBINDING_NOT_FOUND" During technical routing.

No receiver agreement found for sender >> another error in SXMB_MONI

Can you help me, with what needs to be entered in header mapping of received agreement and whether I need to specify anything in Identifiers tab of my Receiver communication channels.
